Abstract
The utility model discloses a single-sided and double-sided battery pole piece rolling mill. The single-sided and double-sided battery pole piece rolling mill comprises a machine frame, two upper bearing seats arranged on the upper portion of the machine frame and two lower bearing seats arranged on the lower portion of the machine frame; and disc spring assemblies are arranged between the upper bearing seat and the lower bearing seat which are arranged on the same side of the machine frame. The single-sided and double-sided battery pole piece rolling mill increases working pressure of a hydraulic cylinder by preloading between two rollers and utilizing disc springs to store mechanical energy, prevents the situation of large pressure fluctuation range when a high-pressure oil cylinder is in a low-pressure working state, guarantees the stability of pole piece compression ratio under the condition that the same compression ratio of single-sided and double-sided materials is guaranteed.
Description
Technical field
The utility model relates to the two-sided battery pole piece rolling mill of a kind of list, especially a kind of milling train of not only can rolling common batteries pole piece but also can the two-sided battery pole piece of rolling list.
Background technology
Battery pole piece is one of critical piece of battery, and the production technology of battery has very high required precision to the thickness of battery pole piece, and namely the pole piece of same thickness should have uniform thickness deviation, also requires evenly excessively when connecting between the pole piece of different-thickness.Battery pole piece rolling mill is the key equipment of producing battery, and it mainly constitutes by frame with by the rack-mounted a pair of milling roller of bearing.Because the battery manufacturing process difference, battery pole piece also has different manufacturing process.Present pole piece milling train commonly used will have certain interval because rolling mill practice requires to go up between the pressure roller, certainly will cause like this when the two-sided pole piece of rolling list, and list is two-sided when crossing roll gap, and the draught pressure difference causes single, double compression ratio difference, influences battery quality.
The utility model content
The technical problems to be solved in the utility model provides a kind of single face, two-sided battery pole piece rolling mill with identical compression ratio that can make single two-sided pole piece.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the two-sided battery pole piece rolling mill of a kind of list comprises frame, is installed in two top chocks of upper rack and is installed in two steps of frame lower; Between the top chock of frame homonymy and step, dished spring assembly is installed.
Wherein, two cover dished spring assemblies are installed respectively between the top chock of frame both sides and step, and two cover dished spring assemblies are installed in the two ends, the outside of top chock and step respectively.
Wherein, described dished spring assembly is by last dish spring bearing, down dish spring bearing, the axis of guide, two are adjusted cover and the dish spring is formed; Last dish spring bearing and play dish spring bearing are separately fixed on top chock and the step, and dish spring and two adjust cover and all are enclosed within on the axis of guide, and the dish spring adjusts between the cover at two, two adjust overlap with the axis of guide between be and be threaded; The bottom of the axis of guide is fixed on down on the dish spring bearing, and its top is inserted in the through hole of offering on the dish spring bearing.
The beneficial effect that adopts technique scheme to produce is: quadruplet dished spring assembly of the present utility model is installed between the upper and lower bearing block, when pole piece is rolling, wedge is thrown off, pressure pressure is offset the precompression of dish spring on the oil cylinder, top and bottom rolls is in quick condition, it is constant to keep-up pressure at the single face of the two-sided pole piece of rolling list with when two-sided, thereby has guaranteed the single face compression ratio identical with double-side material; When rolling common pole piece, adjust wedge and make wedge play the effect of adjusting roll gap, also can rolling common pole piece.Therefore the utility model has improved the range of application of milling train.
The utility model is realized simply, production cost is low; By preload between two rollers, namely adopt dish spring store mechanical energy, to improve the operating pressure of hydraulic cylinder, prevented that high-voltage oil cylinder is in the bigger situation of operating on low voltage state pressure fluctuating range, guarantee the stable of pole piece compression ratio, provide prerequisite for improving the battery product quality.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
See Fig. 1, shown in Figure 2, the utility model comprises frame 4, be installed in two top chocks 11 on frame 4 tops and be installed in two steps 12 of frame 4 bottoms; Install roll 3 on the top chock 11, bottom roll 2 is installed on the step 12; Between the top chock 11 of frame 4 homonymies and step 12, dished spring assembly 9 is installed, and be that transmission side and non-transmission side respectively are equipped with the two ends, the outside that two cover dished spring assemblies, 9, two cover dished spring assemblies 9 are installed in top chock 11 and step 12 respectively in both sides.The output shaft of motor reducer group 7 connects with the roll shaft of topping roll 3 and bottom roll 2 respectively by gear-box 6, two Hooks coupling universal couplings 5.
See Fig. 3, shown in Figure 4, dished spring assembly 9 is used to go up pressing of oil cylinder 10 that precompression is provided, and wedge assembly 8 adjusts to that roll gap is zero between the top and bottom rolls 3,2 during the two-sided pole piece of rolling list, makes bottom roll 2 be in quick condition.Dished spring assembly 9 by last dish spring bearing 9-5, down dish spring bearing 9-1, axis of guide 9-2, two adjust cover 9-3 and dish spring 9-4 forms; Last dish spring bearing 9-5 and play dish spring bearing 9-1 are separately fixed on top chock 11 and the step 12, utilize straight pin to position at bearing block, bolt carry out handle with, with the installation rigidity of assurance dish spring bearing 9-1; Dish spring 9-4 and two adjust cover 9-3 and all are enclosed within on the axis of guide 9-2, and dish spring 9-4 adjusts between the cover 9-3 at two, adjust to be between cover 9-3 and the axis of guide 9-2 for two to be threaded, and adjust the flexible gap that cover 9-3 are used for adjustment dish spring 9-4 for two; Axis of guide 9-2 is used for the location of dish spring 9-4, and the bottom of axis of guide 9-2 is fixed on down on the dish spring bearing 9-1, and its top is inserted in the through hole of offering on the dish spring bearing 9-5.
Quadruplet dished spring assembly of the present utility model is installed between the up-down rollers bearing block, and when pole piece was rolling, wedge was thrown off, and pressure pressure is offset the precompression of dish spring on the oil cylinder, and up-down rollers is in quick condition.It is constant to keep-up pressure at the single face of the two-sided pole piece of rolling list with when two-sided, thereby has guaranteed the single face compression ratio identical with double-side material.When rolling common pole piece, adjust wedge and make wedge play the effect of adjusting roll gap, also can rolling common pole piece.Make milling train improve range of application.
In addition because the foozle of dish spring 9-4, and the adjustment cover 9-3 cause and the gap between the dish spring bearing 9-1 be installed, can cause have between the dish spring pretightning force of transmission side and non-transmission side different, so carrying out the two-sided pole piece of list when rolling, pay special attention to the oil cylinder working-pressure of transmission side and non-transmission side is adjusted, so that pole piece both sides compression ratio is identical.
